[Elecraft] KPA500-KAT500-K3 problem

[Jack Brindle]

The KPA is still set for RADIO= K3, right? Shortly after power up, the KPA will send its on state to the K3 using the Auxbus, but only if it is told the radio is a K3. The symptom is that this is not being received by the K3. The logical conclusion is that something is blocking it. Nothing messed up on pin 2 of the AUX cable, right?

I don't remember if the K3 must be told about the KPA (don't think so, but that would have been long ago...), but if so make sure of that setting.

I'll research this a bit more when I get back to my info system, maybe an hour...
